Bulky pickup in Westminster
Mattresses, furniture, and many appliances — city bulk or drop-off, not the regular cart.
Official source:
Westminster has no city bulky collection. For mattresss, contact your licensed hauler or a junk hauler. The Westminster Sustainability Center accepts some mattresses/e-waste for a fee — confirm current acceptance before hauling. Keep HHW off hauler piles.
Household hazardous waste — used oil, paint, propane, batteries, and chemicals.
Official source:
Westminster has no permanent city HHW depot. Schedule WM At Your Door (appointment; typically ≥3 different materials) or use Adams County spring/fall events. Statewide drop-off: Clean Harbors, 9775 E 97th Place, Henderson (Tue/Thu 9–2; 3rd Sat 9–3 per CDPHE). Keep chemicals off trash.
Yard waste, food scraps, and cooking oil where the city has a separate stream.
Official source:
Westminster does not run general curbside yard-waste collection. Seasonal tree-limb chipping is 2nd Saturday monthly March–November — not grass clippings. Otherwise use your hauler.
Cart recycling, store film take-back, and foam rules — not a second bulky program.
Official source:
Westminster recycling carts do not want expanded polystyrene (EPS). White block foam, packing peanuts, and food trays are different streams. Grocery film/bag bins are not a foam drop-off. City of Westminster — Trash & Recycling is the official Westminster program we verified — if that page only mentions plastic bags or film, treat block foam and food trays as bagged garbage unless it names a foam densifier. Clean peanuts may be reused at a shipper; starch peanuts are not EPS.
